1), by finite element analysis, determine the laying structure of carbon fibre composite sheet material;
2) make the core internal mold of foam material according to the shape of product and size;
3) the laying structure definite according to step 1), by corresponding thermoplasticity carbon fibre composite prepreg voluble wrapping on core internal mold;
4) above-mentioned preform is placed on to heating and mould pressing moulding in mould;
5) demoulding, removes the foam core material of interiors of products, obtains carbon fibre composite luggage carrier.
Described thermoplasticity carbon fibre composite prepreg is that thermoplastic resin and carbon fibre fabric are made by melt impregnation.
Described thermoplastic resin is that heat distortion temperature exceedes the resin of 190 ℃.
Described thermoplastic resin is the one in polyphenylene sulfide (PPS), polyether-ether-ketone (PEEK), polyether-ketone (PEK), polyimides (PI), PEI (PEI) and polyether sulfone (PES).
Described carbon fibre fabric is one or more in plain cloth, twills, satin fabric, one-way fabric, multi-axial tricot.
In described step 3), be also included in the process being wound around and wrap up, steel plate is carried out in bottom.
Compared with prior art, the present invention, by thermoplasticity carbon fibre composite roof-rack is optimized and preparation from being designed into, makes full use of the high strength and modulus of carbon fibre material, improves the strength and stiffness of structure, can also weight reduction.
Accompanying drawing explanation
Fig. 1 is the structural representation that the inventive method prepares.
The specific embodiment
Illustrate below in conjunction with embodiment.
Prepare a kind of carbon fibre composite, comprise the following steps:
1. for technical requirement and the performance indications of luggage carrier, and in conjunction with the performance indications of the thermoplasticity carbon fibre composite that adopts, in finite element software, by adjusting the laying number of plies, direction and the order etc. of carbon fibre composite sheet material, be met the laying design of performance requirement;
2. the core internal mold of producing a set of foam material according to the shape of product inner surface and size, object is the groove of moulding luggage carrier;
3. the thermoplasticity carbon fibre composite preimpregnation band of the laying design according to above-mentioned is wound around and is coated on foam core material internal mold, and at suitable position as steel plate is carried out in bottom, to guarantee its mechanical property;
4. above preform is added in mould, matched moulds heating is carried out hot-forming, heat-insulation pressure keeping;
5. when mold temperature drops to room temperature left and right, carry out the demoulding, the foamed core of interiors of products is removed, obtain the carbon fibre composite luggage carrier of preparation.
Concrete step is:
1) thermoplastic resin adopts PPS resin; Described PPS resin is continuous fiber shape; Carbon fibre fabric adopts one-way fabric, designs by CAE laying, forms the laying scheme that meets performance requirement;
By melt impregnation, PPS resin and carbon fibre fabric are prepared into thermoplasticity carbon fibre composite preimpregnation band; In described PPS/ carbon fibre composite preimpregnation band, the volume ratio scope of PPS and carbon fibre fabric is 0.8:1-1.2:1; The forming temperature scope of described PPS/ carbon fibre composite band is 315 ℃-325 ℃, and preferably processing temperature is 320 ℃; What in described heat pressing and molding mold, mold cores adopted is H13 mould steel;
2) foam core material internal mold: produce the core internal mold of a set of foam material according to the shape of product inner surface and size, object is the groove of moulding luggage carrier;
